decitimers for decennial and annual transitions

here are some countdown timers for a few selected decennial and annual transitional timepoints. the decitimers run as Flash applications prepared with ActionScript3 (acknowledgements to the tutorial that portions of this app were adapted from: 2009 nov/dec volume 5.6).

deciTimer-d0A01 (transition from year NC 12009 to 12010, and from decade NC 12000–12009 to 12010–12019) so long Cordulia decade, and a warm welcome for the Delphastus decade.

deciTimer-d1N01 (transition from year NC 12010 to 12011)

deciTimer-e0A01 (transition from year NC 12019 to 12020, and from decade NC 12010–12019 to 12020–12029) so long Delphastus decade, and a warm welcome for the yet-to-be-designated 'E' decade.

for timepoints occurring at a future time, the decitimers indicate a count toward or until that timepoint.

for timepoints that have already occurred, the decitimers indicate a count from that timepoint.

about the decimal format of time

because the timer number is a decimal representation of time to or from a designated timepoint, each numeric place relates to each other numeric place by a factor or power of 10. this really makes it much easier to readily compare the information from a designated numeric place in terms of another numeric place.

10 hubble in 1 chron, or in 1 day UTC (civil time)

10 tiros in a hubble, 100 tiros in 1 day

10 millichron in a tiros, 100 millichron in a hubble, 1000 millichron in 1 day

10 tok in a millichron, 100 tok in a tiros, 1000 tok in a hubble, 10 000 tok in 1 day

10 tik in a tok, 100 tik in a millichron, 1000 tik in a tiros, 10 000 tik in a hubble, 100 000 tik in 1 day

10 microchron in a tik, 100 microchron in a tok, 1000 microchron in a millichron, 10 000 microchron in a tiros, 100 000 microchron in a hubble, 1 000 000 microchron in 1 day

keep in mind that the above information is listed mainly to show how many different comparisons among common magnitudes can be readily determined using only a particular power of 10. for most practical uses of the decimal representation, it won't be necessary to memorize every possible comparison among the different numeric places. what is important is that you know which clock terms are what magnitude. so a good understanding of a few key terms is essential, and an understanding of other useful terms will be helpful. the particular terms to know readily will depend largely on what clock units you will be using. for civil timekeeping the concept of 'millichron' may very well be essential.

returning to the comparison information above: if you know how a clock unit relates to a clock unit of another magnitude, then you probably understand the magnitude of the units. the point here is that memorization of the comparisons needs to be related to an understanding of the comparisons in a memorable (or meaningful) way.

in contrast with decimal representations of time; try to compare seconds, minutes, or hours in terms of another clock unit. which is longer: 2 hours or 7000 seconds, 8 hours or 500 minutes, 4 days or 100 hours? with a decimal framework of units you can determine a comparison more clearly, and more readily, without as much need for additional calculation.

in any case, best wishes for a fine new year and a fine new decade!


about the dialTiros Java applet

the Java applet shows a local decimal time calculated from your computer clock. the decimal dial differs from the seconds, minutes, and hours (SMH) dial that you are used to.

a quick way to read the dial is to find the major unit value, and then determine the millichron and tok from the minor unit pointer.

one (1.0) tikXn (tikochron) is exactly 0.864 s (second). for additional information about converting to or from decimal and SMH, please reference the AAT ICAS standards.

for official ICAS resources, which include the open source and API for the DialTiros applet, please reference AAT ICAS directly.

use of DialTiros 0.02 is only permitted subject to conformance with 'ICAS in use' and ICAS licensing. terms of use described on this site moreover remain in effect.

why is ICAS date formatting used?

calendar date formats used on this web site are structured to accommodate the reference of calendar dates in terms of either traditional Gregorian or emerging ICAS calendar scales. Universal Time is used for the date-time stamps for web site documents because it is the most common reference time zone.

the datetime stamps used on the web site correspond to standards-validated dates and times. the particular format used for a calendar date is determined in relation to both the source and purpose of use.

interform format ordering (largest to smallest units from left to right) is used as a practical method of communicating datetime information and for accommodating data-interchange. day-of-year numbering is used as a method of noting an always-common factor between the Uniform Calendar and Gregorian calendar scales. other factors that are common to both the Uniform Calendar and the Gregorian calendar, although tabulated differently in each calendar; include the use of a 30-day month, and the use of a 7-day daygroup.

the main practical advantages to using the Uniform Calendar are that date information can be readily abbreviated, expanded, or sorted more easily and more clearly than with the prior traditional calendar formats. experienced users of a Uniform Calendar can also make determinations of the daygroup day for a particular day-of-month more readily, with reference to a uniform daygroup table that can apply to any uniform month. because a leap day is intercalated at the end of a calendar year, common calendrical calculations (such as determining day-of-daygroup, day-of-uniform-month, and day-of-year) can be formulated for the Uniform Calendar in a much simpler manner that does not require additional leap year offsets for the days in a year that follow a leap day.

decimal IDC scale values can accommodate improved calculability and ease of representation in relation to a larger variety of common unit quantities. electronic technologies designed for IDC decimal timekeeping would have no problem representing time values to the more precise decimal scale. for additional information, please see the dialTiros Java applet.

by tradition there are 86 400 seconds in a day. the nearest decimal approximation of a second in terms of a metric main unit of 1 day ('chron' or symbol 'Xn') is 100 000 tikochrons. the exact factor of conversion is: 1 tikochron (tiXn) is equal to 0.864 second (s).

those interested in using ICAS should review their readiness for using ICAS appropriately. read more about the Integrated Chronological Applications System (ICAS) on the official AAT ICAS at web site.


open source 'ICAS now' freeware resources

ICAS software is presently in an early stage of development. any of the following 'ICAS now' resources may be downloaded from the web server as freeware subject to and 'ICAS now' terms of use:

ICAS users should also refer to other ICAS freeware and standards resources available from the official AAT ICAS ( ) web site.
